If type, arch, or os_type are none, we return the default virt type associated with those values. These are typically: - os_type : hvm, then xen - typ : kvm over plain qemu - arch : host arch over all others Otherwise the default will be the first listed in the capabilities xml. This function throws C{ValueError}s if any of the requested values are not found. :param typ: Virtualization type ('hvm', 'xen', ...) :param arch: Guest architecture ('x86_64', 'i686' ...) :param os_type: Hypervisor name ('qemu', 'kvm', 'xen', ...) :param machine: Optional machine type to emulate :returns: A _CapsInfo object containing the found guest and domain linuxrizTHost does not support virtualization type '%(virttype)s' for architecture '%(arch)s')virttyperzLHost does not support any virtualization options for architecture '%(arch)s'rz8Host does not support virtualization type '%(virttype)s'rrz0Host does not support any virtualization optionsNzHost does not support domain type %(domain)s with machine '%(machine)s' for virtualization type '%(virttype)s' with architecture '%(arch)s')r;rrrr7zpHost does not support domain type %(domain)s for virtualization type '%(virttype)s' with architecture '%(arch)s')r;rrr)rh_ ValueErrorrorXrrZr\) r1rXrtypr7rGmsgr;capsinforrr guest_lookupsL    zCapabilities.guest_lookup)NNNN)r r rr]rrrrrFrdrhrorprxrrrrr_s   r_)r-loggerr xmlbuilderrrrrrrrr6r:r?rFobjectrZr_rrrrs  (>
